Research team

My team consists of 11 teachers, including 6 professors, 3 associate professors and 2 lecturers. The team is a united, progressive, innovative and pioneering team formed in more than 20 years since I returned to China in 1992. Nearly 80 graduate students are under the guidance of the team.

The team is divided into four research directions: Existing Bridge soundness evaluation theory, long-span bridge construction control theory and method, composite structure bridge behavior, bridge seismic.

In the above research areas, the team has achieved fruitful results. Among them: the research on construction control theory and method of long-span bridge is in a leading position in China, and the research achievements have won the first prize of national science and technology progress, and have been successfully applied in Sutong Yangtze River Bridge, the world's largest span cable-stayed bridge. The behavior research of composite bridge has made great progress in the aspect of embedded PBL shear connector. More than 200 specimens have been tested and the research results have been successfully applied to Nanjing Yangtze River third and fourth highway bridges. The theoretical research on the soundness evaluation of existing bridges is unique in China. The research idea based on statistical characteristics and bridge type characteristics has made important progress in the research of this problem, and has been approved by experts at home and abroad. Although the research on bridge anti-seismic started late, it has made rapid progress, especially in the aspect of pier water coupling vibration of deep-water bridge, and has won three National Natural Science Foundation and the National Natural Science Foundation of China
